While not as common as skin cancer, colorectal cancer is the third most common cancer in the United States, affecting both men and women. But, like most cancers, understanding risk and early screening can be key to fighting the disease. Not all colon cancers are the same, and at Phoebe, we create custom treatment plans designed specifically to optimize care for each patient we treat.
Most colorectal cancers begin as a growth (polyp) on the inner lining of the colon or rectum.
Some types of polyps can change into cancer over time, but not all polyps become cancer. The types of polyps:
Other tumor types that also begin in the colon and rectum include:
Statistically, colorectal cancers account for over 150,000 new cancer cases each year according to the American Cancer Society estimates.
Overall, the lifetime risk of developing colorectal cancer is about 1 in 23 for men and 1 in 26 for women. However, each person’s risk might be higher or lower than this, depending on their risk factors for colorectal cancer.
Certain risk factors can make it more likely for a person to have certain cancers. Some risk factors – like genetics – are beyond patient control. But other risk factors like diet and exercise may be things you can change.
Family history is a powerful risk factor, and one that patients can use as an important step to understanding their risk. Family history helps medical providers understand whether our own risk for cancers is normal or high, and can be an indicator if additional preventative measures like genetic testing should be included in a prevention regimen. In fact, there are some conditions within family history which automatically makes a patient eligible for genetic testing (such as ovarian cancer, male breast cancer, or an early onset breast or colon cancer).
If you have a family history of colorectal polyps or cancer, you have a higher risk of getting colorectal cancer. Cancer in close (first-degree) relatives such as parents, brothers, and sisters is most concerning, but cancer in more distant relatives can also be important. Having 2 or more relatives with colorectal cancer is more concerning than having only one relative with it. You also may be at elevated risk if your relatives were diagnosed with cancer at a younger age than usual.
Genetic tests can show if members of certain families have inherited a high risk of colorectal cancer due to inherited cancer syndromes such as Lynch syndrome (also known as hereditary non-polyposis colorectal cancer, or HNPCC) or familial adenomatous polyposis (FAP).
In families known to have one of these inherited syndromes, family members who decide not to get tested are typically advised to start routine screening for colorectal cancer at an early age, and to get screened more often. Family members who are tested and are found not to have the mutated gene may be able to be screened at the same age and frequency as people at average risk.
Clearly, knowing your family history is important, so be inquisitive with family members – especially those who have had cancer – to know your risk.
While there’s no definitive way to prevent colorectal cancer, you can make choices and lifestyle changes can help you control and even lower some of the risks. Leading a healthier lifestyle may help lower your risk, including:
For people of average risk for colorectal cancer, experts say screening should start at age 45. Screening may be advised earlier if you are at higher risk. Talk with your healthcare provider about screening to make the choice that’s best for you.
Colorectal cancer may be found with a screening test, helping your physician identify some types of cancer early, before the cancer grows or spreads, often making it easier to treat. There are multiple screening tests used to find polyps and identify colorectal cancer, including:
There are times when we just need to be with a group of people who truly understand our journey and all that comes with it.
